SPECIFICATION forming part of Letters Patent N9.' 728,441, datedMaj-.19, 1903. Appucaaqp'ied January 16,1901; sria1n0l4a459. mamada.)

To all when?, it may concern:

Be it known that I, WILLIAM BUOHOLT, a citizen of the United States,residing at Jamaica, in the county of Queens and State of New York, haveinvented certain new and useful Improvements in Caps for Shade-Roll`marked thereon, which form a part of this specification.

This invention relates to end caps for shaderollers, its object being toprovide a cap which may be adj ustably connected to the roller and whichforms the support for a spring-pressed pin adapted to enter a hole in aninside bracket on the window-casing. Provision is also made to enablethe pin to be retracted in order to disengage it from the bracket.

The invention will be fully described hereinafter, reference being hadto the accompanying drawings, in Which- Figure 1 is a side elevation of`an end portionoi:` a shade-roller with` my improved cap thereon. Fig. 2is 'a 'longitudinal section.` Fig. 3 shows a group ofthe severalpartsdetached. Fig. 4 is a face and edge view of the bracket preferably usedwith my invention.

A indicates the shade-roller, and B a cap.

adapted to fit over the end of the roller. The outer closed end of thecap is centrally perforated, as indicated at b, for the 'passage of apin c, said pin being rigidly connected to or forming part of a disk" C,which ts loosely in the cap. Another disk D, or it may be a bar, issecured within the cap, and in the space between this disk D and thedisk C is a coiled spring E, which, abuts against both disks andnormally holds the pin c projecting through the opening b.

At the closed end of the c ap a series of slots or openings-f are cut atintervals around its periphery, and near the open end' a series ofperforations wgare made around its periphery, these latter being for thepassage of tacks to secure the cap to the roller. The slots g are topermit the insertion vof a knife-blade or bracket to be used with `myinvention.

end wall of the cap to press the disk C back against the force of thespring to disengage the pin o from the bracket.

In Fig. 4 I illustrate a preferred form f s shown, it consists of a flatmetal plate II with a centralopening h for the reception of the pin c.It is also provided with holes Ifor the `passage of nails or screws tofasten it to the casing. In use the plate is nailed in position and anawl 'or other boring tool inserted through the opening h to make a holein the `casing of suii'icient depth to receive the pin c.

It is well .known that the inside Width of window-casings supposed to beuniform vary sometimes as much as lhalf an inch, and if rollers havebeen cut to iit the width the' casings are supposed to be it becomesnecessary on many occasions to either shorten the roller or to block outthe brackets, and this consumes time and in the latter case detractsfrom a neat finish tothe shade-fixtures.

All this is obviated by the use ofmy improved cap, for 'it can beadjusted on the roller to compensate for any such variations, it beingnecessary, of course, to cut the rollers to a length somewhat less thanthelsupposed uniformwidth of the casings. In using the cap it is notpermanently fastened to the roller until it is adjusted to make theroller t the casing, and by omittingv the lastl tack at each endof theroller when securing the shadecloth thereto suchy end tacks may be usedwhen the parts are adjusted to secure the cap in kplace on the roller,as well as the corners of the shade-cloth.

When the caps have been adjusted and secured to the roller, the pin atone end of the roller may be inserted into its bracket and the pin atthe other end be retracted toengage the face of its bracket, and. thenif lthis end is moved over the face of the bracket until the pin isopposite the "openingthe spring will at once project the pin into suchopening.v The roller will be securely supported and cannot beaccidentally disengaged from the brackets, as is the case sometimes whenone or both brackets have openended slots for the reception of the pins,and roo Patented May 19, 190s. ,n

- other-fiat tool between the disk C and the the shade will come incloser proximity to the casing than with brackets now in common use.

Without limiting myself to the precise constructions illustrated, Iclaim- 1. The combination of a cap adapted to be adj ustably tted overthe end of a shaderoller, the end Wall of said cap being centrallyperforated, and said cap having a series of slots arranged peripherallyadjacent said end wall, a movable plate Within the cap having a pin toproject through said central perforation, and a spring supported Withinthe cap to engage the said plate and normally holding the pin projected,substantially as set forth.

2. The combination with a sl1ade-roller,of a cap slidably fitted uponthe end of said roller,

said cap having perforations in its periphery near its inner end for thepassage of tacks into the roller and having also slots in its peripherynear its outer end, and the end Wall of said cap being centrallyperforated, a movable disk Within the cap having a pin to projectthrough said central perforation, and a spring supported Within the capto engage said disk and normally hold it against the end wallof the capWith the said pin projecting through said central perforation,substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
